Cathodic protection to reinforced concrete slab
Cathodic protection to reinforced concrete slab
(OP)
Has anyone any experience with rectifier powered titanium mesh cathodic protection systems applied to the top surface of reinforced concrete slabs?
I did one 20 years ago and so far as I know it is working satisfactorily although I will try to check into that in the new year. It was designed, installed and monitored by a CP specialist firm.
However, on a recent project where we suggested consideration of a rectifier powered titanium mesh CP system to control corrosion on a 60 year old reinforced concrete waffle slab, the client said that they had installed 2 such systems and they failed within a year of installation.

Have done many sacrificial anode packs for steel tanks. Those are limited in time and rarely get replenished as a maintenance consideration.

Was the tank that you did a steel tank or a reinforced concrete tank?
My question related solely to reinforced concrete structures. Sorry if I was not clear enough on that in my original post.
